OS X: Droplings is a free menubar app for the Mac that makes it even easier to share files with friends and colleagues through Dropbox. Just drop a file on the menubar icon, and the app builds a preview page for the file, uploads them both to your Dropbox account, and then drops the URL for the page (with the file on it) in your clipboard.

Droplings' developer built the app because he uses Dropbox to share files with potential clients and coworkers, and likes having a professional-looking preview page for each file he shares. He's made the app free for the time being, while it's in beta, and he noted that there may be a few bugs—we tested it and it works like a charm. That said, he did mention that when it comes out of beta, there'll definitely be a price tag. Still, the beta is free and available now, and requires OS X 10.6 or higher to run.
